这对我有效。只需阻止事件，将URL添加到＜a＞标记，然后在该标记上触发单击事件。

JavaScript

$('.myBtn').on('click', function(event) {
        event.preventDefault();
        $(this).attr('href', "http://someurl.com");
        $(this).trigger('click');
});

HTML

<a href="#" class="myBtn" target="_blank">Go</a>

window.open（）不会在新选项卡中打开，如果它不是在实际的单击事件中发生的。在给定的示例中，URL是在实际单击事件上打开的。如果用户在浏览器中有适当的设置，这将起作用。

<a class="link">Link</a>
<script  type="text/javascript">
     $("a.link").on("click",function(){
         window.open('www.yourdomain.com','_blank');
     });
</script>

同样，如果您试图在click函数中执行Ajax调用，并希望在成功时打开一个窗口，请确保使用async:false选项集执行Ajax调用。

不知怎么的，一个网站可以做到这一点

我将在一定程度上同意下面的人的观点（此处转述）：“对于现有网页中的链接，如果新网页与现有网页是同一网站的一部分，浏览器将始终在新选项卡中打开链接。”至少对我来说，这条“通用规则”适用于Chrome、Firefox、Opera、Internet Explorer、Safari、SeaMonkey和Konqueror。

不管怎样，有一种不那么复杂的方法可以利用对方所呈现的内容。假设我们讨论的是您自己的网站（下面的“thisite.com”），您希望在其中控制浏览器的功能，那么，下面，您希望“specialpage.htm”为空，其中完全没有HTML（这样可以节省从服务器发送数据的时间！）。

 var wnd, URL; // Global variables

 // Specifying "_blank" in window.open() is SUPPOSED to keep the new page from replacing the existing page
 wnd = window.open("http://www.thissite.com/specialpage.htm", "_blank"); // Get reference to just-opened page
 // If the "general rule" above is true, a new tab should have been opened.
 URL = "http://www.someothersite.com/desiredpage.htm";  // Ultimate destination
 setTimeout(gotoURL(), 200);  // Wait 1/5 of a second; give browser time to create tab/window for empty page


 function gotoURL()
 { 
   wnd.open(URL, "_self");  // Replace the blank page, in the tab, with the desired page
   wnd.focus();             // When browser not set to automatically show newly-opened page, this MAY work
 }

不要使用target=“_blank”

始终为该窗口使用一个特定的名称，在我的情况下是指fulName。在这种情况下，可以节省处理器资源：

button.addEventListener('click', () => {
    window.open('https://google.com', 'meaningfulName')
})

这样，例如，当你在一个按钮上单击10次时，浏览器将始终在一个新选项卡中重新阅读它，而不是在10个不同的选项卡中打开它，这将消耗更多的资源。

您可以在MDN上阅读有关此的更多信息。

一个有趣的事实是，如果用户未调用该操作（单击按钮或其他东西），或者该操作是异步的，则无法打开新选项卡，例如，这将不会在新选项卡中打开：

$.ajax({
    url: "url",
    type: "POST",
    success: function() {
        window.open('url', '_blank');              
    }
});

但这可能会在新选项卡中打开，具体取决于浏览器设置：

$.ajax({
    url: "url",
    type: "POST",
    async: false,
    success: function() {
        window.open('url', '_blank');              
    }
});
